Question

Is this relation a function?

A) Yes, for the given x-values, there is one and only one y-value.
B) No, for the given x-values, there is one and only one y-value.
C) Yes, for the given x-values, there is more than one y-value.
D) No, for the given x-values, there is more than one y-value.

Answer 1

D) No, for the given x-values, there is more than one y-value.

Step-by-step explanation:

See the table attached.

The relation given by y = f(x) is not a function, for the given x-values, there are more than one y-values.

This is clear from that for x = - 2, the f(-2) value is 12 and - 15 which is more than one value.

Hence, the relation given in the table between x and f(x) is not a function. (Answer)
